The Little Picture: Ramadan.

Islam's holiest month, which commemorates the revelation of the Qur'an to Muhammad by the Angel Gabriel, begins today. Or, it might begin today -- there's actually a lively debate going on among Muslims as to whether Ramadan's start should be calculated by modern astronomical methods or by the traditional approach of observing the moon with the naked eye. Nonetheless, observances have begun across the globe, from attendance at the Kaaba in Mecca (above) to a mosque in Miami that has chosen to broadcast its Friday sermons on the Internet.
